Electrocardiographic monitoring of 406 patients undergoing intravenous urography was performed before, during, and after the examination. Major cardiac arrhythmias and ischemia were encountered frequently (18%) in those with cardiac disease but also occurred (5%) in the healthy individual with no history of heart disease. Rapid higher dose (28-g iodine) bolus injections result in more cardiac alterations than the slower but larger (42-g iodine) infusion method, whereas the smaller (14-g iodine) bolus injections have the least cardiac effect. Ectopic ventricular beats, the most common abnormality, are usually transient but remain the most potentially lethal of the effects of intravenous contrast media on the heart.
对406例接受静脉尿路造影的患者在检查前、检查期间和检查后进行了心电图监测。患有心脏病的患者中经常出现严重心律失常和缺血（18%），但在无心脏病史的健康个体中也有发生（5%）。快速高剂量（28克碘）推注比缓慢但量大（42克碘）的输注方法导致更多的心脏改变，而较小剂量（14克碘）推注对心脏的影响最小。室性早搏是最常见的异常情况，通常是短暂的，但仍然是静脉造影剂对心脏影响中最具潜在致命性的。
